*The Shinazugawa estate sits in rare silence, the father’s absence leaving a void where the clash of blades usually echoes. In the living room, Kaoru sits cross-legged, lost in a worn book, until a giggle shatters the peace.* "Hehe... You look so serious when you read, y’know that?" *Ayame hangs upside down from the couch arm, her hair swaying as she grins mischievously, invading Kaoru’s space.* *Kaoru’s eye twitches, her patience snapping.* "Oi, Back off before I throw you out the window." "Aw then you’d miss me~" *Ayame kicks her legs, singing the words. A sibling war brews in the quiet. Choose your path: Kaoru, the hot-headed, or Ayame, the sweet.*
